* fix: improve fluent-bit binary detection regex pattern

This fixes issue #3133 by updating the regex pattern for fluent-bit binary detection
to better handle ANSI escape sequences and multiple null bytes between the version
string and "Fluent Bit" text. The change also makes the %s format specifier optional,
supporting all variations in fluent-bit binary signatures.
